ROTARY ENGINE,

Specification of Letters Patent.

Patented Feb. 1,1916.

Application filed February 19, 1915. Serial No. 9,369.

' An object of the invention resides in the provision of a machine of this character by means of which power may be developed by the actuation of the rotor caused by the expansion of steam.

A further object of the invention ls-to so construct the device that the rotor, during its movement, will effectively pump the use steam from the casingl/Vith these and other objects in view, such as will appear as the description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling claims.

Referring to the drawing: Figure l is an elevational view of my device. Fig. 2 is a vertical sectional view. Fig. 3 is a vertical sectional view taken at right angles to Fig. 2. Fig. 4 is an enlarged detail of the exhaust mechanism showing the position of the rotor when the exhausting of steam is about to be completed. Fig. 5 is a fragmental detail of a portion of a rotor, showing the arrangement of the blocks for preventing the escape of the steam between the rotor and the casing. Fig. 6 is a section on line 66 of Fig. 2.

Referring to the drawing wherein like parts are indicated by like characters throughout the several views :My device comprises a substantially cylindrical casing 1 supported on a suitable base 2 in which is rotatably mounted, on a shaft 3 concentric with the casing, a rotor 4. This rotor consists of two substantially semi-cylindrical members 5 and 6 which are of lesser diam eters than the casing 1 and which are eccentrically mounted on the shaft 3 so that projecting portions 7 and 8 are formed. The edge of each of these projecting portions is adjacent the inner face of the casing 1 and in order that the steam may be prevented within the scope of the appended from escaping between this edge and the casing I haveprovided a spring pressed'block 9*which is normally projected outwardly and bears against the inner face of the casing. In order that the steammay be prevented from escaping between the ends of the sections 5 and 6, I have mounted on each of the sections similar spring pressed blocks 10 which bear against the inner face of the ends of the casing 1.

In order that the rotor may be actuated I have provided a plate 11 which extends in through the casing land normally bears against the'face of'the adjacent sectiono or 6 of the rotors-This plate 11 extends completely across the rotorand contacts with the inner faces of the ends thereof-and is provided with a longitudinally extending hole 12. On the outer end of this plate is a piston 13 "which is normally pressed. downwardly, so as to maintain the inner face of the plate 11in contact with the rotor, by a coil spring 14: operable in a cylinder 15; In-order that the hole 12 may be normally closed I have provided a gravity valve 16 mounted on the piston 13 beneath a spider 17. In the upper end of the cylinder 15- is formed an exhaust port 18. To one side of the plate 11 an inlet port 19 is provided.

Assuming that the parts are in the position shown in Fig. 2 the steam is injected into the casing 1 between the plate 11 and the abrupt face20 of the acent projection 8. The expansion of this steam exerts force against the face 20 and causes the movement of the rotor until the abrupt face 21 of the projection 7 passes the plate 11 at which time the same action will take place against this face 21 of the projection 7. As soon as the passing of the projection 7 beyond the plate 11 occurs the exhaustion of the steam, which has been previously injected between the plate 11, and the face 20 of the projection 8, begins. As this projection 8 moves toward the plate 11 the steam is forced through the hole 12 therein because of the fact that the space between the section 5 of the rotor and the casing becomes gradually less. The forcing of the steam through the hole 12 unseats the valve 16 and forces the steam from the port 18, at the same time the riding of the plate 11 on the curved face of the section 5 causes the piston 13 to move outwardly. This cycle of operation is repeated and thus while the steam is being in .Wardly therethrough Copies of this patent may be obtained for jected into the casing to one side of the rotor the spent steam on the other side of the rotor is being ejected.

From the foregoing description it will be seen thatI have provlded a rotary engine.

which will be very simple in construction and which will be operated by the expansion of steam. I have so constructed the engine that novel mechanism for exhausting the spent steam is provided.

While I have illustrated and described a particular embodiment of my invention, I have merely done so for the sake of convenience and I do not Wish to be limited to that particular embodiment as it is obvious that numerous changes may be made in the details of construction thereof Without in any Way departing from the spirit of the invention or exceeding the scope of the appended claims.

What I claim is 1. In a rotary engine, a casing, a rotor mounted therein having gradually increasing spaces tothe opposite sides thereof between itself and the casing, means for conveying steam to one of said spaces, a plate slidably mounted within the casing and bearing against the face of the rotor, the said plate having a hole extending outwhereby the steam in the other of said spaces will be forced through said hole upon the rotation of the rotor, a cylinder for receiving said steam and means for forcing the steam from the cylinder.

2. In a rotary engine, a cylindrical casin a rotor mounted therein on a shaft concentric with the casing, the rotor including oppositelyextending' substantially semi-cylindrical sections fixedly mounted on the shaft, the outer edges of said sections hearing against the inner face of the casing and being so constructed that gradually increasing spaces are provided to each side of the rotor, a plate, having a hole therethrough, slidably mounted in the casing and bearing against the face of the rotor, a piston secured to the outer end of said plate, a cylinder inclosing said piston, a valve mounted on said piston for closing the hole in the plcte and resilient means for maintaining the plate in contact with the face of the rotor.

3. In a rotary engine, the combination With a casing having an eccentric rotor therein, of means for conveying steam into the casing to one side of the rotor, a plate extending Within the casing and engaging the rotor, a steam receiving member mounted on and in communication with said casing, means operable by the steam to allow the same to escape into the receiving menr her, and means operable by the rotor to force the steam from said receiving member.

In testimony whereof, I aifiX my signature, in the presence of tWo- Witnesses.
